Win Sunday’s game at the Chicago Bears, and they win the NFC North and get the home playoff game that goes with it.

But do they really have a chance at Soldier Field if they have to play without some of their key playmakers?

Here are the key injuries to watch this week:

Lacy

RB Eddie Lacy: The Packers’ all-time rookie rushing leader -- he set that mark on Sunday with 84 yards to give him 1,112 for the season -- failed to finish Sunday's 38-31 loss to the Pittsburgh Steelers. He missed the entire fourth quarter after he hobbled off the field, favoring his sprained right ankle. He first injured it on Dec. 8 against the Atlanta Falcons. Although he has not missed a start, he has spent most of the past two weeks wearing a walking boot while practicing only the last two Fridays. “It’s the same thing, reaggravated it,” Lacy said. Backup James Starks was effective in place of Lacy, rushing for 47 yards on 10 carries and catching one pass for 23 yards against the Steelers. Fullback John Kuhn also scored a fourth-quarter touchdown. The only other back on the roster is Kahlil Bell, who was signed on Dec. 3.

Matthews

OLB Clay Matthews: It would seem unlikely the Packers would have Matthews this week and perhaps beyond if they make the playoffs. Matthews reinjured his broken right thumb on his second-quarter sack of Ben Roethlisberger. Matthews knew it was bad as soon as it happened. He ran off the field with his right arm hanging limp at his side. Just like when he broke it on Oct. 6, he couldn’t even use his right hand to unbuckle his chin strap. Matthews needed surgery to fix it the first time and missed four games. “I couldn’t give you a timeline but I think based off the history of what happened the first time, I’m told it’s similar to the [previous] injury," Packers coach Mike McCarthy said Sunday after the game. Adding to the concern is the fact fellow outside linebackers Nick Perry (foot) and Mike Neal (abdomen) are banged up. Neal came out for a portion of Sunday’s game but managed to return.

QB Aaron Rodgers: Need we say anything more about Rodgers? As of last Friday, he had not been cleared to return from his Nov. 4 broken collarbone, which means it will be another week of speculation about his status unless McCarthy says something definitive during his news conference Monday afternoon.
